Data Report for John Bedini's Simplified 'School Girl' Motor and Battery Energizer



Most data is being published under the individual replications pages.


See also the Replications index page.

  • SDA Exp. 21: Thought I had it, but not yet - Solid state charge works better than rotational charge at the same charging current. For the spinning rotor scenario, I implemented most of John Bedini's recent suggestions. Neither test reveals over unity, though the solid state test looked at first like it was going to. 17 pp of data posted. (Dec. 29 - Jan. 3)
  • SDA Exp 10.4 Standing Discharge Rates - Batteries longest on the Bedini Circuit discharged significantly more slowly at first, but then after a day discharged to a lower voltage than those batteries that are more recent to the circuit and lower than one that was damaged early on, and dropped rapidly at first.
  • SDA Exp. 9: Charging with "Zero Current" - Resistor set to 20.8k ohms where the input current is 0.00_ amps, and the output current is theoretically zero as determined by extrapolation of a linear curve drawn from data taken at 0.035, 0.025, 0.015, and 0.005 amps output. Results show no change in battery. (Oct. 29 through Nov. 3, 2004)
  • SDA Exp. 6: Solid State characterization & charging - Experiment to (1) determine the window where solid state (no wheel rotation, but circuit activation by resonance) can take place; (2) supercharge more batteries, seeking optimal solid state charge profile in process. (Oct. 22,23, 2004)
  • SDA Exp. 0: RPMs v Amps - shows a linear relationship between rpm and amps. Double speed of rotor = double amps being drawn from battery (note that this worked because the battery being used was weak enough to not sustain its natural rpm). (Oct. 9, 2004)

  • School Girl motor has to be kick-started. (Other Bedini circuit designs are self-starting; his designs also include solid state iterations.)
  • Increased load on motor draws less amperage from the input battery.
  • The device is not a torque-producing motor but readily runs down when extra load is added.
  • Claim (not proven [actually disproven by the numerous tests run in this project]): the output radiant energy is not picked up by regular instrumentation in the form of increased output current, but the increased charge in the battery does signal the existence of the energy.
  • (not documented)The magnet strength is essentially irrelevant to producing the radiant effect in the coil.
  • (claim, not proven that I know of) Radiant energy does not require conducting materials to flow, but can travel outside the plastic sheath of conduit.


  • Replications - Listing of people who are in process of replicating or who have successfully replicated the device. An index page for each investigator, and a page for each device, with sub-pages for data reports.
